I am a student and was applied for a work from home type job at a firm named astech technology, on 08/06/2019, where i have to type 12000 captcha in 12 days with rs. 2 per captcha. I started typing the captchas but no progress had been shown to me, so i complaint about it but no action had taken. So, i left the job. Now, they call me on 06/09/2019 and demanded rs. 6000, else they would take legal action against me. Now, i don't know what i should do. Please help me.
